How to delete all events in MySQL

Question

If I want to delete some event I need to query something like \"DROP EVENT IF EXISTS eventname\" But I can\'t find the command of deleting all the events at one t

Answer 1

To construct a drop events query, you can do something like this:

select concat('drop event if exists ', event_name, ';') from information_schema.events;

Answer 2

sample one:

DELETE FROM mysql.event
    WHERE db = 'myschema'
      AND definer = 'jon@ghidora'
      AND name = 'e_insert';

https://dev.mysql.com/doc/refman/5.1/en/events-privileges.html

if you can delete the event with DROP EVENT IF EXISTS and re-add it with the new scheduled time.

To permanently delete an event yourself, you can use DROP EVENT:

DROP EVENT [IF EXISTS] event_name

Answer 3

I think you have to use the INFORMATION_SCHEMA.EVENTS table to gather all the active events and then construct and run the DROP EVENT statements.
